Allen Bradley Digital Output Relay Module (P# 1734-OW4)

The Allen Bradley 1734-OW4 is a digital output relay module, a core component within the modular POINT I/O™ system, designed to facilitate robust communication between a PLC and field devices. This module features four isolated relay output channels, providing reliable switching capabilities for higher-power or general-purpose loads. It ensures effective electrical isolation between the control system and external circuits, making it essential for interfacing PLCs with industrial equipment like motor starters, solenoids, and indicator lamps in demanding automation environments.

The Practical Benefits of the Allen Bradley 1734-OW Digital Output Relay Module

The practical benefits of this relay module are found in its ability to safely bridge low-voltage control logic with high-power field devices using mechanical relays. This provides superior electrical isolation and allows for switching both AC and DC loads. Its compact, modular design promotes flexible system expansion, easy installation, and streamlined maintenance in complex industrial control applications.
